Eventually, perhaps, but we're not there yet. While it's still useful it
makes sense to use it.
Seriously? How about when a body part that contributes to the performance

No, the line would be that a man-made replacement for a body part is a
prosthetic. I don't know what the rules should be for prosthetics, but
fairness requires that they not confer an advantage. The rule could be
that runners with prosthetic legs can't compete against runners without
prosthetic legs.

Not a prosthesis, a natural replacement. I don't see a problem with that.

I don't know...depends upon the mechanism and the source of the lean mass.
I don't have a problem with surgical removal of fat mass.

I guess it would depend upon *how* you enhanced and grew these legs, but if
they're genetically human they'd be natural in that the biochemical
processes that created and run them are the same as those that occur in
natural human legs.

``"Natural" for an engine'' makes no sense. Cars are completely man-made,
so the rules governing them will have to be somewhat arbitrary.
I have nothing against performance enhancement due to equipment technology,
doping, man-made body parts, etc. I just think that in order for
competition to be fair, dopers have to compete against dopers, biomechs
have to compete against biomechs, etc.
